Effect of Toxicity of Phthalate Esters during Early Vertebrate Development of Zebrafish (Danio rerio)

Dially I phthalate (DAP) and dipropy I phthalate (DPP) belong to a group of chemicals called phthalate esters (P AEs) which are commonly used as plasticisers. However, higher temperature of the environment is able to break the weak bond of the weak bonding between these chemical with polyvinyl chlor...
